PPK2 Strange Error message at startup

[Simon00]

Hi there

I have noticed a strange error message at startup of the PPK2

11:23:44.790   Failed to get the library versions: JLINKARM_DLL_NOT_FOUND (Origin: "Failed to get module versions.")

11:23:48.361   Validating firmware for device with s/n EA349DCA72C3

11:23:48.368   Opening device with s/n EA349DCA72C3

Why is it even bothering with the JLINK ARM_DLL_NOT_FOUND ??

I do have a Debug pod... ST-Link connected.

Thanks

Simon

works perfectly...

just a big red line in the logs

Ok, thanks. This is not the case on my end, but you might not have installed the nRF Command Line Tools or a supported version of J-Link installed? If not it's recommended you make sure to download those and I think that should resolve your error message.

Wee I'm not using this for a Nordic device  We are using an ST part but about to change.  I saw an article online which raved about the PPK2...  For years now I've looked for something similar and short of spending several thousand dollars on a fluke or similar (which isn't half as good).  But this is a fantastic little tool.

A++ marks for the developer.

installing the online tools changed the messages:

08:14:26.434   Using nrf-device-lib-js version: 0.4.11

08:14:26.434   Using nrf-device-lib version: 0.11.8

08:14:26.434   Using nrfjprog DLL version: 10.15.4

08:14:26.434   Using JLink version: JLink_V7.66a

08:14:26.471   Installed JLink version does not match the provided version (V7.58b).

But why does it even check for JLINK.. its a power profiler, not a debugger / programmer!

Hi

Glad to hear you like it, I'll forward the feedback to the development team!

The reason the Power Profiler app checks for JLink is because the PPK mark 1 needs to be connected to a DK (and the J-Link Interface MCU) to communicate with the computer. So the check is there for backwards compatibility.

Best regards,

Simon
